Application fiie'diua 7, 1921. Serial no. 467,722.

To all whom it may concern:

Be it known that I, HENRY M. SHEER, a resident of Quincy, in the countyof Adams and State of Illinois, a citizen of the llnited States, haveinvented certain new and useful Improvements in Heating Systems forBrooders, lncubatols, and the like, of which the following is aspecification.

This invention relates to heating systems for brooders, incubators, andthe like.

The primary object of the invention is to maintain a constant, uniformand unobstructed flow of oil to the burner.

The further object is to so construct the automatic control that it willefl'ect a higher or lower oil level according to the temperature of theoil.

A further object is to arrange an oilfeeding device adjacent the burner,whereby the carbon forming at the entrance of the oil to the burner maybe broken up, and the oil feeding duct kept clean. H

In the accompanying drawingszfl Fig. 1 is an elevation partly in sectiondisclosing my heating system complete;

Fig. 2 is a bottom plan view of the float;

Fig. 3 is a top planview of the burner base, and support. t

Figure 4 is a top plan view partially in section, of a burner and oilchamber with connection there-between.

Fig. 5 is a detail view of the valve mecha-' nism of the oil chamber,and

Fig. 6 is a vertical section on the line 6-6 of Fig. 1.

The numeral A indicates the main tank; B, the auxiliary supply tank orreservoir; C. the burner support; and D, the burner base.

The auxiliary supply tank B preferably consists of a cylindricalreceptacle divided into upper and lower compartments 1 and 2, beingdivided by a transverse disk 3. The upper end'of the compartment 1 isopen and adapted to receive the main supply tank A, while at the bottomthereof is arranged ascreen or netting spaced therefrom and supportedupon a cylindrical flanged member 5. Immediately above the screen 4 islaced a filtering medium 6, preferably consisting of a heavy cloth, overwhich is placed a quantity of cotton batting or other similar material7.

The partition 3 is thereof with a nipple 8, having it provided centrallydownwardly pro ecting small central opening 9 '26, to the outer end ofend thereof in a T he numeral 11 indicates a terminating at the lowervalve-seat 10.

float constructed of cork or other suitable material, located in thelower compartment 2.

In the central opening 12 of the float is arranged avalve-stem 13secured to a thermostat consisting of'spaced members 14 and 15, thelower member 15 being provided with a threaded stem16 adapted to besecured to a disk 17, the latter being secured to the lower side of thefloat 11 and provided with a plura-lity of openings 18 adapted to permitthe oil to seek its level in the central-opening12.

The upper end of the valve-stem 13 is countersunk and adapted'to receivea highgrade perfect steel ball 19,'the ball adapted to seat itself abouttwo-thirds of its diameter in the valveestem 13. By this construction,when the fuel has risen a sufficient height in the lower compartment.the ball-valve will act to cut off the supply from the uppercompartment.

The purpose of the thermostatic arrangement is to effect a difference inthe relative height of the ball-valve and the float acpensate for theslowness of the flow of oil when cold. 1

The auxiliary reservoir B is preferably supported. upon a base 20provided with a hollow threaded portion21 adapted to receive the hollowthreaded stem 22 secured to the bottom of the reservoir 1 by reinforcingmember 23.

The numeral 24: indicates a threaded disk or lock-nut received upon thehollow threaded stem 22, the former being countersunk on the undersideand adapted to receive a leather washer 25 which is provided withinternal screw-threads, thereby effecting a tight fit between the stemand the locking nut 24. I

Leading from the base 17 is a feed-pipe which is connecte a burnersupport consisting of a 1101 ow u right portion 27 somewhat enlarge at te It is obvious, however, that the valve may be of such a constructi0nas to be entirely concealed within the oil chamber by the re- I movablecap 29.

The numeral 34 indicates a burner base provided with an annular groove35. Extending horizontally from the oil chamber 28 is a hollow tube 36,which communicates with an oil-well 37 arranged beneath and incommunication with the annular oil groove 35. Arranged in the hollowtube 36 is a squared rod 38 adapted to reduce the opening in the insideof the hollow tube 36, and provided with a plurality of ports 36'serving to vent the upper side of the pipe as well as provide a channelfor the oil on the lower side.

The rod is of sufficient length to extend into the oil-well 37 at oneend, and. within the oil-chamber 28 at the opposite end, bemg providedat this end with a transverse opening 39, whereby when the cap' 29 isremoved, the squared rod 38 may be oscillated or shifted to distributeany, sediment or sluggish oil which may accumulate.

"If desired, the burner may be entirely re- 1 moved for cleaning, itbeing merely necessary to close the valve 32, thereby eliminatmg thenecessity of changing the oil control ad'ustment at the reservoir.

Anot er advantage of having a valve below the oil chamber in the burnersupport is that it enables one to fill the annular oil groove of theburner, together with the'oil chamber, with gasoline or the like, forstartng, and prevents thecharge from finding its way intothe oil feedplpe, thereby reducmg the amount of gasoline necessary to start.

In operation, the reservoir is adjusted to such ahei ht with respect tothe supporting base as to1 ring the 011 in the compartment contalningthe float on a level with the openmg 1n the hollow tube. 36 adjacent theburner at which level the ball-valve is seated oil tothe lowercompartment.

upon the valve-seat 10, cutting ofl the flow v To vary the height of theoil in the float compartment and the oil chamber 28, it is only necessato adjust the'height of the reservoir 1 with respect. to the base 17. Toreduce the oil level in the float chamber, a

lock-nut 24 is unscrewed, and the container or reservoir 1 is screweddown or turned to the right, while raising or turning to the left willincrease the height of the oil in the float chamber and correspondinglyincrease the flow of oil to the burner, or rather it increases theheight of the oil in chamber 28. WVhen the proper height is de-'termined, lock-nut 24 is screwed down holding the container 1 in theadjusted position. The thermostatic arrangement on the float proper isto effect an additional oil regulation between the burnerfand thecompartment B, which is determined by the temperature of the oil, thethermostat proper expanding and contracting accordingly. This 15desirable to compensate for the slowness of the flow of the liquid whenthe oil is cold.
